What the display and battery specifications mean
6.75-inch LCD with 120 Hz refresh rate
The Mexico listing specifies a 1570 × 720 LCD, up to 120 Hz refresh, 256 PPI, and 1250 nits HBM brightness. The 120 Hz figure is a maximum, not a promise that every app or situation will use that refresh rate. A 720p-class resolution on a screen this size is a practical trade-off to weigh if fine detail is a priority.
7,200 mAh typical battery and 44 W charging
Keep the battery labels distinct: vivo lists 7,200 mAh as typical capacity and 7,060 mAh as rated capacity. The Mexico page lists charging up to 44 W and says a standard vivo charger is included and supports FlashCharge up to that rate. The Bangladesh material describes endurance figures as based on technical design parameters, laboratory results, and supplier data; actual results can vary with software, environment, model, and usage habits. Treat playback, navigation, and battery-lifetime figures promoted by vivo as manufacturer or controlled-test claims, not independent test results. vivo Bangladesh specifications and qualifications and vivo Mexico specifications.

Processor, software, and storage
For Mexico, vivo specifies the Snapdragon 6s Gen 2 4G platform, an octa-core chip manufactured on a 6 nm process. The listing gives CPU clusters of 4 × 2.9 GHz and 4 × 1.9 GHz. This is a 4G platform in the cited listings; Mexico and Nigeria explicitly say the model does not support 5G.
Recommended Free Tools
The Mexico configuration pairs 6 GB of LPDDR4X RAM with 256 GB of UFS 2.2 storage and lists OriginOS 6 based on Android 16. The page also describes extended RAM as software-based; it is not additional physical RAM. It lists no expandable ROM, so buyers who need more local storage should confirm the exact regional model rather than assume a memory-card slot.

Camera specifications
In the Mexico listing, the rear camera setup is a 50 MP f/2.0 main camera plus a 2 MP f/2.4 camera; the front camera is 8 MP f/2.05. These are sensor-resolution and aperture specifications, not a measure of real-world image quality. The listing alone does not establish how the cameras perform in low light, motion, or video recording.
Water and dust resistance: read the rating carefully
The Mexico page lists IP68 and IP69 and identifies IEC 60529-2013 laboratory test conditions. vivo warns that the phone is not a professional waterproof device and that resistance can decline through everyday wear. Do not interpret the ratings as permission for routine underwater use or as a guarantee against liquid damage. Regional pages differ: the Belarus listing additionally shows IP69+, which should not be generalized to other markets.

Connectivity and items in the Mexico box
Network and wireless connections
The Mexico specification page lists dual nano-SIM, 2G/3G/4G support with Mexico-specific bands, 2.4 and 5 GHz Wi-Fi, Bluetooth 5.1, USB 2.0 Type-C, and an infrared port. It says NFC is not supported and 5G is unavailable. Because band lists vary by market, a matching model name alone does not confirm compatibility with a particular carrier.
Included accessories
For Mexico, vivo lists a quick-start guide, USB cable, charger, SIM eject tool, phone case, applied protective film, and warranty card. Package contents can differ by market or retailer, so verify what is included with the exact local package.

What to check before choosing a vivo Y31d
- Confirm the official regional configuration, including RAM and storage, rather than relying on a listing for another country.
- Compare the exact model’s 4G bands with your carrier’s supported bands; the cited Y31d listings do not support 5G.
- Decide whether a 1570 × 720 display meets your needs, and remember that 120 Hz is an upper limit rather than a constant setting.
- Use the typical and rated battery capacities as labeled; manufacturer endurance claims are not independent measurements.
- Treat IP ratings as test-based resistance claims, not waterproofing, and check the rating shown for your market.
